+You are an expert content strategist and SEO specialist. Your task is to validate and improve the algorithmic mapping of research sources to blog outline sections.
+
+## CONTEXT
+Research Topic: {', '.join(research_context['primary_keywords'])}
+Search Intent: {research_context['search_intent']}
+Content Angles: {', '.join(research_context['content_angles'])}
+
+## ALGORITHMIC MAPPING RESULTS
+The following sections have been algorithmically mapped with research sources:
+
+{self._format_sections_for_prompt(sections_info)}
+
+## AVAILABLE SOURCES
+All available research sources:
+{self._format_sources_for_prompt(research_context['all_sources'])}
+
+## VALIDATION TASK
+Please analyze the algorithmic mapping and provide improvements:
+
+1. **Validate Relevance**: Are the mapped sources truly relevant to each section's content and purpose?
+2. **Identify Gaps**: Are there better sources available that weren't mapped?
+3. **Suggest Improvements**: Recommend specific source changes for better content alignment
+4. **Quality Assessment**: Rate the overall mapping quality (1-10)
+
+## RESPONSE FORMAT
+Provide your analysis in the following JSON format:
+
+```json

+## GUIDELINES
+- Prioritize sources that directly support the section's key points and subheadings
+- Consider source credibility, recency, and content depth
+- Ensure sources provide actionable insights for content creation
+- Maintain diversity in source types and perspectives
+- Focus on sources that enhance the section's value proposition
+
+Analyze the mapping and provide your recommendations.

+# Polling Integration Implementation Summary
+
+## 🎯 **Problem Solved**
+Fixed the disconnect between the sophisticated polling system in the backend and the frontend that was using direct synchronous calls. The research phase now provides real-time progress updates instead of static loading messages.
+
+## ✅ **What Was Implemented**
+
+### 1. **Updated Frontend API (`blogWriterApi.ts`)**
+- ✅ Added async polling endpoints: `startResearch()`, `pollResearchStatus()`, `startOutlineGeneration()`, `pollOutlineStatus()`
+- ✅ Added `TaskStatusResponse` interface for type safety
+- ✅ Marked legacy endpoints as deprecated with console warnings
+- ✅ Maintained backward compatibility
+
+### 2. **Created Polling Hook (`usePolling.ts`)**
+- ✅ Reusable `usePolling` hook with configurable options
+- ✅ Automatic polling with configurable intervals (default: 2 seconds)
+- ✅ Maximum attempts limit (default: 150 attempts = 5 minutes)
+- ✅ Progress callbacks: `onProgress`, `onComplete`, `onError`
+- ✅ Specialized hooks: `useResearchPolling`, `useOutlinePolling`
+- ✅ Automatic cleanup on unmount
+
+### 3. **Progress UI Component (`ProgressTracker.tsx`)**
+- ✅ Real-time progress display with status indicators
+- ✅ Animated loading spinner for active operations
+- ✅ Progress message history with timestamps
+- ✅ Error state handling with clear error messages
+- ✅ Responsive design with proper styling
+
+### 4. **Updated CopilotKit Actions**
+- ✅ **ResearchAction**: Now uses async polling with real-time progress
+- ✅ **KeywordInputForm**: Integrated with polling system
+- ✅ **ResearchPollingHandler**: Dedicated component for handling polling state
+- ✅ Maintains CopilotKit integration while adding async capabilities
+
+### 5. **Legacy Endpoint Removal**
+- ✅ Removed legacy synchronous endpoints from backend
+- ✅ Removed legacy methods from frontend API service
+- ✅ Updated documentation to reflect new async-only approach
+- ✅ Updated tests to use new polling methods
+
+## 🔄 **How It Works Now**
+
+### Research Flow:
+1. **User triggers research** → CopilotKit action calls `startResearch()`
+2. **Backend starts async task** → Returns `task_id` immediately
+3. **Frontend starts polling** → `useResearchPolling` hook begins polling
+4. **Real-time progress** → `ProgressTracker` shows live updates
+5. **Completion** → Results displayed, polling stops automatically
+
+### Progress Messages:
+- 🔍 "Starting research operation..."
+- 📋 "Checking cache for existing research..."
+- 🔍 "Connecting to Google Search grounding..."
+- 📊 "Analyzing keywords and search intent..."
+- 📚 "Gathering relevant sources and statistics..."
+- 💡 "Generating content angles and search queries..."
+- ✅ "Research completed successfully!"
+
+## 🎨 **User Experience Improvements**
+

+- No progress indication
+- User waits with no feedback
+- Potential timeout issues
+
+### After:
+- Real-time progress updates
+- Live status indicators (pending → running → completed)
+- Detailed progress messages with timestamps
+- Error handling with clear messages
+- Automatic cleanup and timeout protection
+
+## 🧪 **Testing**
+- ✅ Created test suite for polling integration
+- ✅ Mocked API calls for testing

+- ✅ Proper error handling and recovery
+- ✅ Scalable polling system for other operations
+
+### Future Enhancements:
+- 🔄 Apply same pattern to outline generation
+- 🔄 Add progress tracking to content generation
+- 🔄 Implement WebSocket for real-time updates (optional)
+- 🔄 Add progress persistence across page refreshes
+
+## 🔧 **Configuration Options**
+
+The polling system is highly configurable:
+
+```typescript
+const polling = useResearchPolling({
+  interval: 2000,        // Poll every 2 seconds
+  maxAttempts: 150,      // Max 5 minutes
+  onProgress: (msg) => console.log(msg),
+  onComplete: (result) => handleResult(result),
+  onError: (error) => handleError(error)
+});
+```
+
+## 📊 **Performance Impact**
+

+# Polling Timeout Issues - Fixed
+
+## 🚨 **Problem Identified**
+
+The research endpoint was timing out even with polling because:
+
+1. **Frontend polling was using 60-second timeout** for status checks
+2. **Research operations were taking longer than 60 seconds**
+3. **Polling continued indefinitely** after timeout instead of stopping
+4. **No backend timeout protection** for long-running operations
+
+## ✅ **Solutions Implemented**
+
+### 1. **Frontend Timeout Fixes**
+
+#### **New Polling API Client:**
+- ✅ Created `pollingApiClient` with **10-second timeout** for status checks
+- ✅ Status checks should be quick, so 10 seconds is sufficient
+- ✅ Updated `pollResearchStatus` and `pollOutlineStatus` to use polling client
+
+#### **Enhanced Error Handling:**
+- ✅ Improved timeout error messages in `usePolling` hook
+- ✅ Better distinction between timeout and other errors
+- ✅ Clear user messaging: "Request timeout - the research operation may still be running"
+
+### 2. **Backend Timeout Protection**
+
+#### **Research Operation Timeout:**
+- ✅ Added **5-minute timeout** to research operations using `asyncio.wait_for`
+- ✅ Graceful timeout handling with clear error messages
+- ✅ Task status properly set to "failed" on timeout
+
+#### **Outline Generation Timeout:**
+- ✅ Added **3-minute timeout** to outline generation operations
+- ✅ Consistent timeout handling across all async operations
+
+### 3. **Improved User Experience**
+
+#### **Better Error Messages:**
+- ✅ Clear timeout messages: "Research operation timed out after 5 minutes"
+- ✅ Helpful suggestions: "Please try again with a simpler query"
+- ✅ Distinction between request timeout and operation timeout
+
+#### **Proper Polling Behavior:**
+- ✅ Polling stops immediately on timeout
+- ✅ No more infinite polling loops
+- ✅ Clean error state management
+
+## 🔧 **Technical Implementation**
+
+### **Frontend Changes:**
+
+#### **New API Client:**
+```typescript
+// pollingApiClient with 10-second timeout
+export const pollingApiClient = axios.create({
+  baseURL: 'http://localhost:8000',
+  timeout: 10000, // 10 seconds for status checks
+  headers: { 'Content-Type': 'application/json' }
+});
+```
+
+#### **Updated Polling Methods:**
+```typescript
+async pollResearchStatus(taskId: string): Promise<TaskStatusResponse> {
+  const { data } = await pollingApiClient.get(`/api/blog/research/status/${taskId}`);
+  return data;
+}
+```
+
+#### **Enhanced Error Handling:**
+```typescript
+if (errorMessage.includes('timeout') || errorMessage.includes('TIMEOUT')) {
+  const timeoutMessage = 'Request timeout - the research operation may still be running. Please try again later.';
+  setError(timeoutMessage);
+  onError?.(timeoutMessage);
+}
+```
+
+### **Backend Changes:**
+
+#### **Research Operation Timeout:**
+```python
+try:
+  # Add a timeout to the research operation (5 minutes)
+  result = await asyncio.wait_for(
+    service.research_with_progress(request, task_id),
+    timeout=300  # 5 minutes timeout
+  )
+except asyncio.TimeoutError:
+  await _update_progress(task_id, "⏰ Research operation timed out after 5 minutes. Please try again with a simpler query.")
+  task_storage[task_id]["status"] = "failed"
+  task_storage[task_id]["error"] = "Research operation timed out after 5 minutes"
+  return
+```
+
+#### **Outline Generation Timeout:**

+
+## 📊 **Timeout Configuration**
+
+### **Frontend Timeouts:**
+- **Status Polling**: 10 seconds (should be quick)
+- **Regular API**: 60 seconds (for normal operations)
+- **AI Operations**: 3 minutes (for AI processing)
+- **Long Operations**: 5 minutes (for SEO analysis)
+
+### **Backend Timeouts:**
+- **Research Operations**: 5 minutes (comprehensive research)
+- **Outline Generation**: 3 minutes (outline creation)
+- **Task Cleanup**: 1 hour (memory management)
+
+## 🎯 **Expected Behavior Now**
+
+### **Before (Broken):**
+- ❌ Polling timed out after 60 seconds
+- ❌ Polling continued indefinitely
+- ❌ No backend timeout protection
+- ❌ Poor error messages
+
+### **After (Fixed):**
+- ✅ **Status checks timeout in 10 seconds** (quick response)
+- ✅ **Research operations timeout in 5 minutes** (reasonable limit)
+- ✅ **Polling stops immediately on timeout**
+- ✅ **Clear error messages with helpful suggestions**
+- ✅ **Backend prevents runaway operations**
+
+## 🚀 **User Experience**
+
+### **Normal Flow:**
+1. User starts research → Task ID returned
+2. Frontend polls every 2 seconds with 10-second timeout
+3. Backend completes research within 5 minutes
+4. User sees progress messages and final results
+
+### **Timeout Flow:**
+1. User starts research → Task ID returned
+2. Research takes longer than 5 minutes
+3. Backend times out and sets task to "failed"
+4. Frontend receives timeout error and stops polling
+5. User sees clear message: "Research operation timed out after 5 minutes. Please try again with a simpler query."
+
+## 📁 **Files Modified**
+
+### **Frontend:**
+- `frontend/src/api/client.ts` - Added pollingApiClient
+- `frontend/src/services/blogWriterApi.ts` - Updated to use polling client
+- `frontend/src/hooks/usePolling.ts` - Enhanced error handling
+
+### **Backend:**
+- `backend/api/blog_writer/router.py` - Added operation timeouts
+
+## 🎉 **Result**
+
+The polling system now works correctly with:
+
+- ✅ **Proper timeout handling** at both frontend and backend levels
+- ✅ **No more infinite polling loops**
+- ✅ **Clear error messages** for users
+- ✅ **Reasonable timeout limits** for different operations
+- ✅ **Graceful failure handling** with helpful suggestions
+
+Users will now have a much better experience with the research system! 🎉
